My understanding of the abstract syntax is that the following RDF Graph is
not part of OWL DL.
<a> <b> _:v .
<a> <c> _:v .
_:v <d> <e> .
i.e. the use of blank nodes in OWL DL is approximately that permitted in
RDF M&S without the new rdf:nodeID construct.
I think this is a mistake.
RDF Core found that the inability to serialize an arbitrary graph in the
official syntax was somewhat embarrassing, I think WebOnt should learn from
that embarrassment.
Suggested fix, permit individualID,and perhaps classID to be a blank node
identifier in abstract syntax.
